r is the number of objects from the total n objects that you want to permute.

For example, if I have the set of characters \{a,b,c,d\}, I can choose to permute any of up to 4 of the characters. Suppose I take just 2 of them. Then the formula predicts I should find {}_4P_2=\dfrac{4!}{(4-2)!}=\dfrac{24}2=12 possible permutations. Indeed, these are

\begin{matrix}ab&ac&ad\\ba&bc&bd\\ca&cb&cd\\da&db&dc\end{matrix}

You have 2\3 of a pizza left from yesterday. You divide it into 4 equal pieces. What fraction of the pizza is each piece?​

2/3 / 4 = 2/3 / 4/1 = 2/3 × 1/4 = 2/12 = 1/6

so each quarter of the remaining 2/3 pizza is actually 1/6 of the complete pizza.
